Application April 29, 1932.. Serial No. 08,284 1 Claim. (01. 20-42)- Thepresent invention relates to improvements in bull boards for railwaystock cars, and has for an object to provide an improved bull -boardwhich will be held securely locked in operative position and .may bereadily unlocked and relooked, promoting great facility in the movementand operation of the bull boardand enhancing its security wheninoperative position.

Another object of the invention is to provide an'improved bullboardwhich may with great readiness be removed to an inoperative positionleaving the doo'r opening clear for; the passage of the cattle.

A further object of the invention resides n.

providing an improved construction of cardoor frameforcooperatingwiththe improved bull, board, whereby the bull board isoperated free ly and easily and when in theupper position is With theforegoing and other objects in'view, the invention will be more fullydescribed hereinafter, and will be more particularly pointed out in theclaim appended hereto.

V In the drawing, wherein like symbols refer to like or correspondingparts throughout'the several views,

Figuregl is a fragmentary side view of a rail 1 way stock car with partsin section showing the improved bull board in operative position acrossthe door opening. j

l igure 2 is a vertical section taken'on the line 2-2 in Figure l.Figure 3 is a horizontal section taken 'on the line 3-3 in Figure 1, and

Figure 4 is a longitudinal. section taken through the improved bullboard.

Referring more particularly to the drawing 5 represents generally arailway stock car having a side door opening 6, and 7 represents thestandards or sillsat the sides of the door openmg.

In accordance -with the invention channel frames are provided inconjunction with the ceiving'the improved bull board. 7

As shown; in Figure 3 the sills '7 at outer corner portions thereof arerecessed or cut away In the recesses are provided channel frames ormembers having bases 10 fitting against the bases 8 of the recesses andfurther having inner The inner flanges upper portion or are set sidesills or uprights 7 for .the purpose of re flanges 1 1 and outer H theshoulders flanges 11 are. fitted snugly against 9; while-the outerflanges 12 supply the place of: any .outerwalls for the recessesandconfine thelbull boardatits outer side. Screws or other fastening means,12 are driven through .thebases 10 0f the channel frames and intothenprights v These v channel frames, as. shown" in Figures Land 2,extend down to a point belowthe central part of the door opening 6 wherethe same terminate. The recesses also 13 are inserted in the terminateand filler strips.

lower portions of the recesseslin order to receive and support thelower. stop ends 14 of thechanfra s. 7. h p er more particularly H paranof the iffc anneilr'ram s are, provided ba'ckwardly and downwardlyoffset pockets for receiving the lower edge of. the bull 7 board. Thesepockets are formed by wide upper head portions 15 of 11 are discontinuedat the which extend diagonally downward and inwardly of the car wherebyto form guides for directing the bull board. into the pockets. Thediagonal flanges 16 at their lower parts extend forwardly lower parts ofthe pockets and constituting rests locking means for retaining the bullboard in the inoperative position.

The hull boardpreferably consists of a plank or board 19 of suitablelength, breadth and thickness reinforced with sheet metal or otherappropriate material. The sheet metal is indicated at 20 as extendingover the front face of the board 19 and having the strips 21 and 22extending over the upper and lower edges of such bull board.

The innerface need not be reinforcednor need the. ends of the bull boardbe reinforced with the metal as such ends do not come'in contact withthe bases 8 of the channel frame but anti-friction rollers23;,preferably carried in pairs at eachend of the bull board are ar-"ranged to roll upon the bases '8 to facilitate the the channel framebases 8..

back into flanges ld to provide bottom. ledges 17 for forming theraising and'lowering of the bull board. These rollers 23 are fitted inslots 24 provided in the ends of the board and the rollers roll upon"pintles 25 carried by the board and the metal reinforcing plate 20.Rivets or other approto hold the I stop shoulders so for engaging.against the bull board to prevent the rotation of the latches inaclockwise direction as looked at in Figure 2-.

In the use of the invention the operative position of the bull board isshown in full lines in Figures 1 and 2. In this position the bull board,

rests upon the bottoms 14' of the 'channel'frame and extends across thedooropeningxG at an.

In this position the bull board is held in place by means of the latches27..

intermediate point.

These latches are simply forced forwardly the full limit of theirmovement until the shoulders, encounter the inner edge of the bullboard; whereby the movementof the latches will be arrested. Meantime thecam surfaces.

29' have been moved into frictional binding engagement with the upperreinforcing edge of the bull board. The latches will thus be jammed intoplace. The bull board cannot be raised as the latches cannot be rotatedin this direction owing to the position of the pivots 28 and theengagement of the shouldersi); nor can the, latches back offduetothe'jammed" frictional engagement thereof. Thus the bull board willremain looked despite the jarring and shocks incident to travel ,of thecars. When the bull board is to, be raised the latches 27 are forcedback ""to the position shown in' dotted lines in Figure 2. The bullboard can then be lifted up in the tracks or channel frames until thesame arrives at the uppermost position whereupon the lower part of thebull board is pushed backwardly allowing such lower part to descend intothe pockets and to rest upon the ledges.

17, being confined by the upstanding ends 18 of the flanges. In thisposition the bull board will remain without any likelihood of its accidental falling. r I V 'When the bull board is to be restored tooperative position it is raised so that its lower part will clear thewalls 13. The bull board is then moved into a position registering withthe channel frames and it may thereupon descend until resting upon thebottoms 14.. V

Itis obvious. that various changes and modifications may be made in thedetails or construction andfdesi n of the above specifically describedembodiment of this invention without '.departing from the spiritthereof, such changes and modifications being restricte scope of thefollowing claim.

What is claimed' is:- In combination with a railway stock car having aside door opening, channel frames at the sides of theopening havingbottoms, pockets offset rearwardly and: downwardly from the upperportionsof saidlframes; rear diagonal flangesv for said"pocketsfdownwardly sloping ledges forming bottoms for the pockets;upstanding curbs atv the forward portions of the pockets, and a bullboardslidable vertically in said: frames-for resting upon thebottoms andadapted to be cantedrearwardly into thepockets back of said curbs.
